Which Launch Title Would Make You Buy a PS4?

That illustrious Sony press event on February 20th is just one week away, and with the PS4 reveal entirely possible (in a huge venue nonetheless), we wanted to end our three weeks of PS4 questions on the games. So, the PlayStation LifeStyle staff was asked:

Are we sure there will be one? I mean, look at the history of Naughty Dog. Crash 1-3(PS1), Jak and Daxter 1-3(PS2), Uncharted 1-3(PS3). Those are main games sure, but they seem as if they like making new trilogies for each generation.

The thing I'm wondering about the next gen consoles is, for example, whether we'll see a second round of titles like Crysis 3 come out for them. You know, it'll initially launch on PS3, 360 and PC ... but then down the road will the new consoles get a version with improved graphics, etc. !!! Ya? Na?
